SALIVA EJECTOR.

Application led February 27, 1923. Serial No. 621,550.

To all whom t may concern.'

Be it known that I, 'FRANK L. DATLEY, a citizen of the United States, residing at New Brunswick, in the county of Middlesex and State of New Jersey, have invented certain new and useful Improvements in Saliva Ejectors, of which the following is aspecification.

Various attempts have been made heretofore to produce a saliva ejector which would function efficiently and with a minimum of discomfort to the patient. The problem is to guard the saliva intake against obstruction by the soft tissue of the mouth .and yet permit the ejector to lie snug against the floor of the mouth. The ordinary ejector hasa substantially ball shape mouth-piece which is very discomforting to the user and is not effectively guarded. Another form of ejector has a guard or overhang of the full section of the body. It not only fails of its purpose, but is very discomforting to the patient and moreover is readily broken. The object of my invention is to provide a saliva ejector which shall be free` from vthe objections and disadvantages stated and which can be 'manufactured and sold at small cost.

The accompanying drawings show, on an enlarged scale, two embodiments of the ink vention.

Figure l is a perspective View of one form of the invention, a portion of the body being broken away.

Fig. 2 is an elevational view, partly` in section, of the structure, Fig. l.

Fig. 3 is a perspective view of another form of the invention.

Fig. 4L is an elevational view, partly in section, of the structure, Fig. 3.

The saliva ejector, F" a tubular body member 5 having a bent arm or gooseneck 6 the ultimate portion ofy j which is disposed at an angle to the straight body portion 5. The presence of the angle in lieu of the usual curvature, which would cause the terminal portion to parallel the body, is of advantage in that it facilitates positioning the arm under the tongue and keeping it there with a minimum of angs. l and 2, includes noyance to the patient. The end of the arm isl open the full diameter of the bore and constitutes a saliva intake 7, which is fended by a flaring lip or guard 8. The latter is formed by a flat or plate-like extension of the under portion of the tube; said eXtension having a broad bridging portion 9 in spaced relation with the intake'and whereof the wings 10 eventuate in the taper 1l overlying the tube.

In the embodiment ofthe invention, Figs. 3 and l, the curved arm l2 .is formed with a saliva intake or orifice 13 in that wall adjacent the body, the end of the arm being closed and eventuating in a flaring lip 14: similar to that previouslydescribed, and which overlies the orifice in spaced relation thereto.

A further merit of the guard of this invention is that, since its basal part springs from the main element and the guard is otherwise free or in floating relation with said element, it admits of expansion and contraction and hence obivates breaking, in the case of aglass tube, when the tube is boiled or sterilized.

Having described the nature and object of the invention, I claim l. A saliva ejector including a tubular member having a short arm or mouth piece the ultimate portionof which is disposed at an angle to the main body portion, said mouth piece having al saliva intake a wall of which is flattened and reversed to constitute a guard for the intake, the terminal of the guard overlying the opposite wall of the intake, but floated with respect thereto to provide for expansion and contraction.

2. A saliva ejector including a tubular member having a short' arm or mouth piece open at the end to constitute a saliva. intake having the full cross-sectional area of the tube, and means for guarding said intake, said means consisting of an integral leaflike extension of a wall of the intake bent to overlie the intake in spaced relation thereto and having its terminal overlying, but unattached to the tube.

In testimony whereof I affix my signature.

YFRANK L. DAILEY.
